NATIONAL CONSUMER COMMISSION TO ASSESS COUNTERFEIT SAFETY CRITICAL DEVICES CASE

F ollowing the conviction on June 2 this year of Abdool Kadar Omar Khan (55), the importer of 124 000 counterfeit CBI circuit breakers and earth leakage devices, the matter is now being “assessed” by the National Consumer Commission (NCC) in Pretoria. The Commissioner’s office issued a statement to Sparks Electrical News affirming that, “arising from the finalisation of the criminal matter against Abdool Kadar Omar Khan, the sole proprietor of Akronix and South Star Technologies, the NCC’s Investigations Unit will assess the decision of the court and make representations to the NCC’s Screening Committee for a possible reinstatement of its [the NCC’s] investigation in terms of the Consumer Protection Act, which was put on hold at the request of CBI to allow for the criminal matter to proceed unhindered.” CBI “CBI welcomes the NCCs proposal to look into reinstating the investigation and we will provide our full support and cooperation,” says Andrew Dickson, divisional manager: engineering and quality, “Adherence to compulsory specifications is important in keeping people and property safe, and we hope that the NCC continues to work together with industry for the benefit of the South African consumer,” adds Dickson. Recall The NCC could not comment on questions put to the commissioner regarding a recall of the unsafe counterfeit products as it would be “premature to comment on the questions raised by your publication at this stage”.

the extent of the risk. This, in my opinion, is the responsibility of the entities that sold the products, the National Regulator for Compulsory Specifications and the National Consumer Commission,” Nothard says. He adds that there is “an incomprehensible unwillingness of organisations to combine resources towards the common goals”. “This applies within the industry and to the authorities’ apparent top- down approach and reluctance to work with industry to resolve the scourge of dangerous products on the market.” Apathetic “It is my personal opinion, from experience, that we have a significantly apathetic electrical industry that complains a lot but seldom takes the

The counterfeit non-compliant devices of the accused were tested and all of them failed to comply with the requirements of VC 8035 and VC 8036. Khan imported 124 000 counterfeit products from the Peoples’ Republic of China between 21 September 2009 and 21 November 2011 and sold the devices to various electrical companies. According to court documents, this placed more than 25 000 businesses and homes at “significant risk”, including fire, electrocution and death. To date, none of the products has been recalled. Product recall Pierre Nothard, chairman of the SAFEhouse Association, says “identifying all the locations of the counterfeit devices is probably impossible”. “At the very least, a substantial publicity campaign to recall the products should be conducted to reduce

PERSONALITY OF THE MONTH: LOUIS PRETORIUS VASBYT … THE GOOD TIMES WILL SOON BE HERE

Sparks: What is your favourite quote? LP: The one that jumps to mind is, in Jan Brand’s famous words ,“Byt vas, beter tye is oppad”. Sparks: Name three things on your ‘bucket list’ (things you want to do before you ‘kick the bucket’). LP: I would like to do a course in scuba diving and go diving at the coast; tour the country; and start brewing my own beer. The big one, however, is to avoid kicking the bucket!

Sparks: What major projects have you worked on and what is your greatest accomplishment? LP: Being involved in a training centre, we have done a number of development projects, the biggest being the development of the ECA (SA) national office, which was quite a learning curve. To me, every student I have assisted in becoming a qualified artisan is an accomplishment. When I’m out and about or at an ECA(SA) branch meeting, it’s a good feeling to be approached by people who say, “Hello Mr Pretorius,” and remind me that I trained them years ago. Sparks: Have you won any awards? LP: Does long service count? No, I have not received anything worth mentioning. Sparks: Who has been your inspiration or have you had a mentor who has influenced your career? LP: I can honestly say that I have not had anyone who has inspired me. Unless I can mention the time that my late father told me to “get a job or … …” then it would be true to say that he inspired me. Tom Kearns, my first training manager, was a great mentor who taught me a huge amount about how to work and deal with people. Sparks: What, to your mind, is one of the biggest challenges facing the industry at this time? LP: The current economic and political situations in the country are big challenges because we need economic and political stability to ensure growth. Sparks: What do you enjoy most about your job? LP: I enjoy the diversity in my position. I never know what will happen next when the phone rings or there is a knock on my door. Sparks: How do you motivate your staff? LP: Nowadays I don’t motivate anymore; I just threaten! Sparks: If you could “do it all again”, would you change anything? If so, what would that be? LP: Yes, I would change something: I would have continued studying. But, as they say, hindsight is a perfect science. Sparks: Would you advise a person leaving school to enter the electri- cal industry? And why? LP: Yes I would. There are so many opportunities. Look at me. I started out as an electrician but I am no longer working in the trade. I do, how- ever, still have my qualification as an electrician.

Louis Pretorius

LOUIS Pretorius, the regional director (Highveld) for the Electrical Contractors’ Association of South Africa – ECA(SA) – has been a loyal, dedicated employee at the Association for more than 22 years of the 40 that he’s been involved in the electrical industry. Louis is proudly one of the ‘old school’ electricians who demands perfection from his students – not because he wants to make their lives difficult but because where electricity is involved, there are no short cuts and anything short of perfection is just not good enough. This is why he’s highly respected in the electrical industry – students who pass through his hands always make the grade and they remem- ber him with a great deal of respect and gratitude. Sparks: Where were you educated? LP: I was educated at Goudrif High School in Germiston and then went onto study at technical colleges in Germiston and Kempton Park. I completed a diploma in training through Damelin and am also a reg- istered assessor and moderator. Sparks: How long have you been involved in the Industry? LP: I have been in this industry from back in the days when General

Sparks: What is your advice to electrical contractors? LP: Hang in there, plan ahead. Better times are upon us.

Tyres was still a ‘Private’. Seriously, though, I’ve have been involved in the industry for 40 years, 30 of which I have spent in the training sector. Currently, I am responsible for all the training at the ECA(SA)’s head office in Meadow- dale. Sparks: When and where did you start your career? LP: I started work in July, 1974, at what was then known as the General Electric Company. I spent the first six months working as a fitter and turner but prior to completing my two years of compulsory service in the army, I contacted my training officer and told him I wanted to be an electri- cal apprentice. The rest is history. Sparks: What are the greatest changes you have seen over the years? LP: Number one must be the advances in technology; and two, the decline in the standard of workmanship. courageous steps necessary to bring about changes. If CBI had not been determined and involved, this conviction may not have been obtained. I therefore take my hat off to CBI for its commitment and action in this case.” Consumer Protection Act South African consumers’ rights are enshrined within section 55 (d) of the Consumer Protection Act No 68 of 2008 (CPA), which states: “… every consumer has the right to receive goods that … comply with any applicable standards set under the Standards Act, 1993 (Act No 29 of 1993), or any other public regulation …” CONTINUED FROM PAGE 1

WORKING KNOWLEDGE BY TERRY MACKENZIE HOY

THE GRID – BALANCING GENERATED POWER AND CONSUMED POWER

the Eastern Cape alone there are more than 65 000 km of power lines rated at 66 000 V and above. There are about 1 500 km of 765 kV power lines and it is inter- esting to note that Eskom was the first public utility in the world to successfully operate 765 kV power lines at altitudes above sea level. It is important to make sure that people have access to electrical power that is virtually uninterrupted. At the same time, it would be uneconomical to make power lines so robust that they will not fail. Consequently, Eskom has a huge maintenance staff that can restore electricity after a failure. Failures can result from fires, lightning strikes, equipment faults and so on. We can comprehend the apparent scale of the National Grid

I THOUGHT that, in my August column, I would discuss the South African National Grid, normally referred to by Eskom as ‘The Inter- connected Power System’. A number of things should be understood: first, apart from a few seconds worth of stored energy in the form of rotating machines (ie motors) the grid cannot store energy. What comes in goes out again virtually instantaneously. Thus, there is always a balance between the power generated and the power consumed. Second, all the generators – that are not wind turbines or solar PV plants – feeding the grid are fitted with governors. These keep the generators at constant speed and whether or not you are connecting the city of Johannesburg or switching on a light bulb in the kitchen somewhere, in the grid a governor has operated to allow you to do this.

The size of the grid can be seen as follows: On an electricity bill one will see that consumers are charged in Rands per kilowatt hour, which is effectively the average kilowatt demand over an hour at a given rate. An average house uses 13 kWh per day. The peak kilowatt demand in South Africa in midwinter is about 38 000 000 kW, more often writ- ten as 38 000 MW or megawatts. To compare, in France it is about 90 000 MW and UK about 55 000 MW. The majority of power generated is from coal power stations lo- cated in Gauteng, Limpopo, North West and Mpumalanga. Koeberg nuclear power station is in the Western Cape and there are a num- ber of gas turbine stations in coastal towns and a few hydro sta- tions. Not generally understood is the massive extent of the grid. In

when we consider that the energy consump- tion of South Africa is the same per capita as the combined consumption of Botswana, Na- mibia, Zambia and Zimbabwe. Apart from hydro plants, lately there has been growth in the in- stallation of wind turbines and solar photovol- taic power plants. At the end of 2014, there were 1 600 MW of wind and solar power plants in operation. How- ever, because the sun doesn’t shine at night and wind doesn’t blow all the time, these installa- tions only supply power intermittently and, on windless nights, the power supply has to come from a different source – either hydro or coal. Experience in other countries has shown that wind power can be so variable from year to year that it’s virtually unreliable and, in September 2014, the 12 000 MW capacity of Britain’s wind turbines generated less than 1% of the rated output due to lack of wind. Wind turbine sup- porters accuse the press of sensationalising the lack of output of wind turbines during those oc- casional periods when the wind doesn’t blow. This is really not the point. As mentioned earlier, consumers expect the power supply to be virtually uninterrupted – thus, for every wind turbine built, one has to build alternative power generation. Since it is not possible to start-up a coal-fired station quickly, the generation has to be gas turbine, which has very high fuel con- sumption. Because of this high fuel consumption, gas tur- bines are only needed under emergency condi- tions; and, since these conditions generally arise when the wind is not blowing, for some of the time the gas turbine is producing no income at all. While there are arguments for and against wind turbines, there is one irrefutable fact: wind turbines will not replace current generation. What will replace it will be discussed in my next column.

THE DECENT HYDRAULIC CRIMPER

If quality is what you’re looking for, then look no further than the hydraulic crimper from Rennsteig, a subsidiary of KNIPEX. This quality German-made two-hand tool easily crimps copper and aluminium conductors with cross-sections from 10 to 400 mm 2 . The crimper is 600 mm long and has a 180° rotating head; and its 80 KN crimp force makes it the ideal tool for electricians – even for the most demanding crimp jobs. A comprehensive range of crimp dies is also available.

GETTING TO GRIPS WITH SANS 10142-1 BY HANNES BAARD

IF I CAN’T TRUST THE SYSTEM TO PROTECT ME, WHAT IS THE USE OF THAT SYSTEM?

I n my July column, I ended without going into any detail regarding Regulation 4. Just to confirm … this is the fourth clause of the Electrical Installation Regulations that forms part of the Occupational Health and Safety Act (Act 85 of 1993). Just as well, for now we have a nice warm topic to heat up our winter discussions. Hopefully it will not turn into a hot potato. So, without any further ado … let’s first look at the Regulation and then dissect it. Functions of approved inspection authorities for electrical in- stallations 4. (1) An approved inspection authority for electrical installations may enter premises and conduct an inspection, test or investigation only when (a) Contracted by the chief inspector or provincial director for a spe- cific electrical installation; or (b) Requested by the user or lessor of an electrical installation to do so. (2) An approved inspection authority for electrical installations may not operate as an electrical contractor. In my humble opinion, the regulation is very clear. First, it says, no AIA can enter a property to do any kind of inspection without proper sanc- tion. The AIA has to be either contracted by the chief inspector of the Department of Labour, or invited by the user or lessor of the electrical installation to conduct an inspection and compile a report. But wait, how did the AIAs come about? Well, it is clear that be- cause many government departments cannot do what they are supposed to do, they get someone else to do their job for them. Forget about the fact that we pay taxes to enable electrical law enforcement to be done by a particular government department in the first place. Now here’s the thing: who pays this AIA for services rendered? Pardon me if I sound a little harsh or even blasé on this topic but if someone comes into my premises, he or she will need a very good reason and they would have to be in possession of all the required paperwork. Now, let’s assume that because I am a good and oblig-

ing citizen, and after some contemplation, I allow the AIA onto my premises, it does not mean that I have to pay that AIA as, in my opinion, there is no contract between us. But wait, does the govern- ment actually pay these AIAs? And does the entity that requests such an AIA to come and do an inspection, expect to pay for a service by an agent of the government? Maybe not … It may be a little ridiculous to think like this, but it’s like asking the SAPS to investigate a disturbance at your neighbour’s house and then getting a bill for it. At last count there were only about three of these electrical AIAs in South Africa. So few? Yes, Perhaps the government makes it difficult for anyone to enter this law enforce- ment arena that was not part of the original pilot scheme. So, how do these few AIAs make money if the same Regulation says they may not operate as an electrical contractor? 5. (1) No person may authorise, design, install or permit or require the installation of an electrical installation, other than in accordance with a health and safety standard incorporated into these Regulations un- der section 44 of the Act. If we look closely at subregulation (1), we can see that even if a person who thinks it’s okay to install something that‘s not completely in accordance with the stipulations in SANS 10142-1, for example, because the owner or user of the electrical installation requested, suggested or even allowed a lower standard, can land one (or both them) in hot water. How so, you ask? The words ‘authorise’, ‘permit’ or ‘require’ speak to the owner or user and the words ‘design’ and ‘install’ speaks to the installer – be it a contractor or a person in the contractor’s em- ploy. Think of it as though someone says it’s okay to take another person’s life and you are stupid enough to believe him and go and do it … it does not make it right! 5. (2) No person may use components within an electrical installa- tion unless those components comply with the standards referred to Now, let’s move on to Regulation 5: Design and construction

in the relevant incorporated standard referred to in subregulation (1), and proof of compliance shall be identifiable on the components or certification shall be available from the manufacturer or supplier of the materials or components in terms of the National Regulator for Compulsory Specifications Act, 2008 (Act No. 5 of 2008). This is easier than it sounds. What is encouraging, though, is that the front page article in the July 2016 issue of Sparks Electrical News recounts the story of an importer who was convicted for importing circuit breakers that do not comply with this subregulation. But what can I do if, for whatever reason, something goes wrong and it is found after a fire, for instance, that the circuit breaker I installed did not comply? Well, my personal stance would be that I have my proof of purchase from a reputable supplier. I do not think the legislator intended that I, the end-user, would have to chase the paperwork for each and every little item I use in an electrical instal- lation. After all, there is a regulation and enough is written within the Occupational Health and Safety Act itself that forbids anyone to import, manufacture or sell anything that does not comply with a standard. And, as the end-user, I am surely not required to use some kind of comparison mechanism to determine the authentic- ity of the manufacturer’s stamp or the SABS mark on the product purchased. If I cannot trust the system higher up to protect me, what is the use of that system then in the first place? 5. (3) Items of an electrical installation not covered by an incorporated health and safety standard, and the conductors between the point of supply and the point of control, shall be installed in accordance with the by-laws or regulations of the supplier concerned. For all those guys who, after a previous column, wondered where I got it from that the supply cables from the point of supply to a point of control may be installed under a slightly different set of rules … well, here they are. This goes for the main earthing arrangement in the installation, too. If the supply authority says you will install it in a certain way, you have no grounds to argue. Therefore, within reason, stop arguing … just do it! Till next time.

USA-based Band-It – a leading manufacturer of a full range of stainless steel band, buckle systems, preformed clamps and cable ties for numerous applications. It is also the only company that dis- tributes the Ultra-Lok product range, the Band-It Ultra-Lok tool and open-end clamps.

CABLE theft in South Africa is a huge problem, however, Matthew Campbell of Banding & ID Solutions Africa explains that the security of any traditional cable installation can be increased by using the Ultra- Lok clamp. “The Band-It Ultra-Lok clamp is a robust clamping solution, with a tamper-proof design. It is easy to install, and can drastically de- crease cable theft.” He explains that the efficacy of the Ultra-Lok clamp was proved at a client’s site last year. “The client operates in the petrochemical industry where conveyer belts are located in secluded areas and

are difficult to monitor so cable theft is a major challenge. We dem- onstrated the Banding & ID Solutions Africa product offering and it was decided that the Ultra-Lok open-end clamp would be the best way forward.” Banding & ID Solutions Africa has been tasked with supplying the client with application tools and clamps, and will provide training for the operators who will install the clamps.

Acquisition enhances power generation business capabilities

T he acquisition of Generator Technologies (Gentech) by Marthinusen & Coutts has fur- ther enhanced this Actom division’s capacity; this time specifically on the power generation side of its operations. The acquisition was effective March 01, 2016. Gentech was established in 1990 and over the past 26 years established a reputation of providing professional service to most of the African conti- nent and the Middle East. Its operation has been integrated into Marthi- nusen & Coutts’ existing power generation facil- ity in Benoni. This 14 000 m 2 facility is based at 28 Lincoln Road, Benoni. Mike Chamberlain, operations executive for Marthinusen & Coutts, says that the acquisition has enabled the division to bring additional valued skills and equipment on board and will strengthen Marthinusen & Coutts’ capability. Notably, Gentech is well respected in the sugar industry. Its previous owner, Butch Mezker has been appointed as general manager of the Marthinusen & Coutts Electrical Power Generation Division. Mezker holds government certificates for mechanical and electrical engineering and has extensive experience with all types of generators. The Marthinusen & Coutts Electrical Power Generation Division now comprises two operations; the Benoni operation and its Sasolburg-based mechanical repair facility, ACTOM Turbo Machines. The latter facility was brought on board following the acquisition of Cetus Turbo Machinery in November 2014. Together, these operations provide complete electro-mechanical solutions to customers. The acquisition of Generator Technologies (Gentech) by Marthinusen & Coutts has further enhanced this Actom division’s capacity; this time specifically on the power generation side of its operations.

MARK PALMER - ELECTRICAL APPROVED INSPECTION AUTHORITY SOUTHERN AFRICA (EAIASA)

AN OUTLINE OF THE AIA PROCESS T his month, I’m going to deviate from the topic I’ve covered in my last few columns – the clarification of the fundamen- tal requirements of SANS 10142-1 – and look at the current

some registrations. Of further concern, however, is the fact that many registered persons and electrical contractors are not familiar with the legislation that is applicable to them and some have opted to follow ill-given advice from people who are opposed to the AIA process. ‘From the horse’s mouth’ The Department of Labour can be contacted directly where any confusion exists relating to this process. Email Pieter Laubscher, deputy director for electrical engineering at the directorate, electrical and mechanical engineering, Department of Labour at Pieter.Laubscher@labour.gov.za The Electrical Approved Inspection Authority Southern Af- rica (EAIASA) offers training programmes at its Cape Town and Johannesburg regions that cover the application of legislation, SANS 10142-1 and the issuing of CoCs. Registered persons and electrical contractors are urged to attend these programmes in or- der to obtain valid information ‘from the horse’s mouth’ and thereby avoid the legal implications that may arise due to misguided advice.

at the cost of the registered person or electrical contractor involved in the matter. • The above process is mandated to the AIA to resolve within a period of 14 working days. • Should the matter not be resolved in the required time, the matter would be further investigated by the DoL and, where necessary, con- ditional withdrawal of registration as an electrical contractor would be done with a further extension of 14 days being given to resolve the matter. • Should this further opportunity given to the registered person or electrical contractor still not have the desired outcome, the matter will be forwarded to the Specialist Public Prosecutor. • Where multiple complaints against a registered person are received, the process also allows for the DoL to instruct a registered person to undergo further training, which could include re-writing the instal- lation rules. The above processes are already resulting in positive outcomes in situations where electrical contractors have ignored non-compli- ance notices issued by an AIA and the DoL has already withdrawn

changes being implemented in the electrical Approved Inspection Authority (AIA) process prescribed by the Department of Labour (DoL). The DoL, in an effort to clarify its policing mechanisms of stand- ards within the electrical contracting industry, recently invited stake- holders to a workshop to discuss some anticipated changes to the mandate given to the AIAs by the DoL. Although many of the stakeholders have for years been an in- tegral part of the AIA process discussion groups, it has become increasingly apparent that a certain segment of the contracting in- dustry is still not in favour of an external accredited and approved policing structure. Self-regulated environment Within this opposition, it is also clear that a self-regulated environment is being sought, even though this avenue proved unsuccessful when attempted after promulgation of the Electrical Instal- lation Regulations in 1992.

Notwithstanding this small segment of opposi- tion, it is obvious that if active AIA policing is not supported by all stakeholders, those who may ‘suf- fer the consequences’ are the ultimate benefactors of a compliant electrical contracting industry: the consumers. Secondly, the duly registered electrical contractor suffers the same fate when cracks in the system allow for non-registered contractors to openly ply their trade on an uneven playing field. That said, I believe that current mechanisms are starting to yield positive results and perhaps will lead to improvements in current legislation when the Electrical Installation Regulations are reviewed. It is my opinion that the AIA’s functions will be en- hanced to lend further support to the legitimate contracting industry. The workshop highlighted the need for AIAs to play a more expansive administrative and techni- cal role in addressing complaints received from the public as well as industry where, in particular, invalid Certificates of Compliance (CoCs) are issued. The DoL further reiterated that the AIAs should be regarded as an extension of its inspectorate and that any registered persons and electrical contractors, who were contacted by an AIA after an investigation had declared an issued CoC as invalid, have a legal responsibility to react to that communication. It was further indicated that failure to react to the communication would lead to direct DoL involvement in the matter. Legal processes The DoL further indicated that a process document would shortly be made available to the industry wherein all legal processes would be clearly outlined to all who are affected by the issue of CoCs and the policing thereof. As many of these processes are already being used by AIAs, here is a summary of the current processes: • A complaint should be directed to either the DoL or an AIA. • Dependent on the nature of the complaint, the DoL could refer a complaint directed to them to an AIA for further investigation. • The above process is in line with the provisions of the Electrical Installation Regulations where the functions of the AIA are prescribed accordingly. • After an investigation has been concluded by the AIA, the AIA has the authority to declare an issued CoC as invalid and request the user to obtain a new CoC. • The registered person and/or electrical contrac- tor would, in terms of the process, be contacted by an AIA and given the opportunity to re-inspect the electrical installation, attend to all required remedial work and then issue a new valid CoC. • As these complaints would already be in the DoL’s domain, it would, however, be required that the AIA validate the new CoC in order for the DoL to con- sider withdrawing the complaint against the regis- tered person or electrical contractor. • The above validation inspection would, however, be

P & T Technology supports the CHIETA’s drive to assist people who have the required electrical, theoretical and work experience evidence and support them through the Recognition of Prior Learning (RPL) process. This CHIETA-funded project aims to assist competent electricians, who meet the required criteria, to obtain a trade test certificate. The RPL process involves multiple steps, which includes pre-evaluation (screening test) and preparation (‘brush up’ training over five weeks) and culminates in a trade test.

RELAY TESTING SYSTEM IS QUICK AND EASY TO USE T he FREJA 500-series is the newest mem- ber of Megger's relay testing equipment Megger and the rugged hardware design is

nine current channels are required. The FREJA 549 includes four voltage channels and six cur- rent channels making it possible to test genera- tor protection with differential and undervoltage. The four voltage channels are also needed when testing auto-reclosers with synchro-check. The current capability of these channels must not be skimped – testing a 5 A relay at six times rated current means that a minimum of 30 A is needed, but the capacity to work at even high- er currents is useful in many applications. Old electromechanical protection relays are still in

generators the FREJA 536 provides a complete three-phase test system for commissioning of three-phase protection systems. The FREJA 536 can provide six current generation, and FREJA 549 can provide nine current generation, by converting the voltage channels to currents. The generators also provide high power in both the voltage and current channels to test virtually all types of protection relays. For testing three-phase differential relays, six current channels are needed and, for conveni- ent testing of some special applications, up to

With three current generators and three voltage

widespread use, and pushing high test currents through these depends on the test set being able to deliver a high output compliance voltage – up to 50 Vrms is highly desirable. Of course, as well as looking to the past with electromechanical relays, it’s also important to look to the future and take into account protection schemes based on the IEC 61850 standard. Most users will not, at present, require facilities for test- ing these schemes, but they will want to know that their test set is future proof and that it will, when the time comes, support IEC 61850 testing. Many test sets are designed to be controlled by a PC and for complex tests this is often the best option. Indeed, Megger offers its widely used FREJA Win software for just this purpose. For simpler tests, however, it is often useful if the test set can be operated as a self-contained unit. The best test sets make autonomous operation very convenient by providing large colour display screens and clear controls. Whether the test set is operated autonomously or with a PC, its software is intuitive in operation, and a recent development of particular value is ‘wizard’-based functionality, as is offered by FREJA Win. This allows the test engineer to set up the instrument for routine tests simply by an- swering a series of straightforward questions. It then provides guidance during the performance of the test, flagging unexpected conditions and results, and providing clear advice on appropriate remedial action. Finally, the FREJA 500-series is capable of generating clear and comprehensive reports in a format that allows the test results to be conveni- ently shared. For more information, contact Megger.

TRAINING AND DEVELOPMENT BY NICK DU PLESSIS

WIREMAN’S LICENCES FOR FOREIGN PERSONS B efore I begin, let me clarify that the term, ‘wireman’s licence’, is the registration by the Department of Labour of registered persons. It is important to make this quite clear as I received to make application with the Department of Labour to become reg- istered persons.

Authority (SAQA) and the practical qualifications verified by ESETA accredited providers”. The problem is that when applying, most applicants are stymied when they get to the section of the document that defines the cri- teria and the applicant then fails to complete the final part of the document and miss the evaluation and verification requirements. In this article, I will explain the process that all foreign applicants should follow in order to address the criteria of section 4 of the from the Department of Labour brochure (OHS 3/1/5/7/9 Revised March 2014). Foreign candidates should firstly ensure that they have all their theoretical foreign qualifications evaluated by the South Africa

Registration criteria The Department of Labour has set out the registration criteria that a person must comply with in order to be registered by the chief in- spector as an ‘Electrical Tester for Single Phase’, ‘Installation Elec- trician’ and ‘Master Installation Electrician’ as defined in the Elec- trical Installation Regulations, 2009 promulgated by Government Notice R242 of 6 March 2009, and section 4, foreign qualifications, states that “candidates are required to have all their theoretical foreign qualifications evaluated by the South Africa Qualification

an email from a Member of Parliament reprimanding me for refer- ring to it as a ‘wireman’s licence’. However, I will use this term as it is still known as a ‘wireman’s licence’ in the industry and because this article is directed at foreign persons who wish to operate in the electrical industry in South Africa. As we are all aware, times are tough in the electrical industry in South Africa as well as in the rest of Africa and many foreigners are coming to South Africa to look for a better life. This has become evident from the many enquiries I receive from foreigners who wish

Qualification Authority (SAQA). This is done by going to the SAQA web page on www.saqa.org.za (http://41.193.15.87/dfqeas/user/home. Value chain The purpose of the evaluation is that foreign qualifi- cations are recognised in terms of the South African National Qualifications Framework (NQF). SAQA performs this function as an integral part of a national recognition value chain. The focus of SAQA’s role is on the location of foreign qualifica- tions within the NQF. Evaluation is a two-phased process by SAQA to firstly, verify foreign qualifications by ensuring the following: • Issuing bodies are accredited and recognised with- in the national systems in which they operate. • Qualifications are legitimately issued by those is- suing bodies and part of the national qualifications of that country. • Qualifications documents are in order and awards claimed by individuals are genuine. • Compare foreign qualifications with South African qualifications, considering the structure and out- comes of the foreign qualifications, to locate them within the South African NQF. The second process is for foreign candidates to have all their practical qualifications verified by EWSETA- accredited providers. This requires that candidates check with the EWSETA that has been accredited to conduct evaluations of foreign qualifications. The EWSETA provider then checks the SAQA compari- son of the foreign qualifications with South African qualifications and, based on this, the provider would verify that the candidate has the practical abilities linked to the awarded NQF qualification. Practical assessment An example of this would be if SAQA indicated that the foreign qualification is NQF 4 equivalent then the provider would put the candidate through a practical assessment equivalent to a trade test. The purpose of evaluating the qualifications is to ensure that the ap- plicant has the level of knowledge and experience as well as practical ability aligned to the NQF 4 equiva- lent qualification. It must be remembered that, in South Africa, we have our own regulations and standards and the function of the EWSETA provider is to ensure that foreign candidates will be able to apply the rules and regulations when they obtain their registration. It is for this reason that the Department of Labour has incorporated section 4 into the requirements of the registration process. The EWSETA-accredited provider is legally obliged to ensure South African standards and regulations are known by foreign candidates who are applying for registration; and the EWSETA pro- vider will provide a statement of results in a letter addressed to the Department of Labour verifying that the practical skills of the foreign applicant have been evaluated. During these difficult financial times, it is of criti- cal importance that all electrical work is undertak- en by registered contractors and that a registered person has exercised general control over all elec- trical work and a valid Certificate of Compliance has been issued.

NO EXCUSES FOR INDUSTRY ELECTRICAL INCIDENT INJURY AND DEATH

Eskom, has contributed to his expertise in this field. Ngwenya has identified three definitive causes that increase risk and contribute to unnecessary electrical injury or death. He cites these as inadequate training; complacency; and perceived time constraints. “There is simply no excuse for any of these,” Ngwenya says. Surgetek, a South African specialist in lightning and surge pro- tection, electrical safety, test and measurement equipment and, more recently, personal protective equipment (PPE), is committed to reducing electrical injuries and deaths. Ngwenya says he has found a partner in his employer – one that shares his vision of zero electrical injuries and deaths in South Africa. With Surgetek’s back- ing, he now has the platform to promote safety protocol adherence; to bring new electrical safety equipment and PPE to market; and to provide adequate training to all personnel – new and experienced.

ees and refresher training for more seasoned employees. In addi- tion, we use training to remind electrical industry personnel of the importance of following safety protocol – aimed to minimise the complacency aspect.” Ngwenya aims to drive this through to the experienced technicians, engineers and senior personnel. He adds that, contained within customer-specific equipment safety training, emphasis on overall safety methods and proce- dures are constantly reinforced. “For example, there is nothing so critical that it has to be done immediately – there is always time to don the required, approved PPE and follow all safety protocols, while using the necessary safety equipment – correctly. We need this message to be clearly understood,” he emphasises.

Individuals to blame Ngwenya points out that every organisation conduct- ing work in the electrical sector is governed by inter- nal rules and regulations that enforce compliance with the Occupational Health & Safety (OHS) Act. This is to minimise risk to personnel and safeguard them during the course of their work. “However, no individual can be policed 24/7,” he points out. “This means that the onus to comply with all protocol gov- erning electrical work ultimately falls to individual employees, some of whom are ill-prepared and, con- versely, others over-confident. The consequences are electrical injuries and fatalities.” Training, reinforcement and proper attire The company conducts customer-specific, knowl- edge-based training on all its products at dedi- cated training facilities at its Randburg office. “We advocate training for all customers’ new employ-

THE number of incidents causing injury or death in the electrical in- dustry is totally unacceptable and can be avoided, says Sikhumbuzo Ngwenya, high voltage divisional manager, Surgetek. “There are no jus- tifiable reasons why any safety-related electrical incident should ever occur,” he adds. A registered professional engineer with the Engineering Council of South Africa (ECSA), Ngwenya’s significant industry experience as a network security planning engineer focusing on power line outage studies, fault levels, contingency plans, emergency pre- paredness plans, essential loads, management and execution of manual and automatic load shedding at utilities electricity provider, Sikhumbuzo Ngwenya, high voltage divisional manager, Surgetek, is adamant that the electrical injury and fatality rates can be brought to zero through proper and adequate training.

Innovative low-voltage circuit breaker makes small-scale microgrids a cost- effective option providing an all-in-one solution I n a world first, ABB, a leading power and automation technology group, is making it pos- sible for microgrids to be protected, controlled and managed using smart circuit break- ers. A software-based innovation for the company’s Emax 2 smart circuit breaker makes microgrid architectures simpler and more cost-effective than ever before. Microgrids coordinate distributed energy resources, integrating renewables with conventional power sources, networking with the grid or operating self-sufficiently. Low- voltage microgrids are helping accelerate the roll out of renewable energy by integrating small scale wind or solar energy production of up to 4 MW with battery energy storage systems. Giampiero Frisio, managing director of ABB’s protection and connection business, says, “This is another technological first for ABB, building on the first ever combined circuit breaker and power manager Emax 2. Innovation is needed to make microgrid installations simpler and more cost-effective; and to help end-users get more value from their investment. By embedding all the

intelligence needed to manage a small microgrid safely and productively, Emax 2 delivers a game-changing solution.” With the addition of embedded functions such as an automatic transfer switch, Emax 2 is now equipped to manage the different power sources that make up a typical microgrid. The new upgrades to ABB’s Emax 2 cir- cuit breaker will enable it to combine advanced protection, programma- ble logic, full connectivity, easy integration and comprehensive microgrid energy management in a single device. ABB is working with equipment suppliers and consultants ahead of the technology’s roll-out in the sec- ond half of 2016. This all-in-one solution integrates standard and advanced microgrid functionalities to meet a broad range of on- and off-grid requirements, improving quality and saving costs. A complete series of protections ensure a single unit can cover all loads and generators, with adaptive protections that recognise network changes and automatically set new thresholds to guarantee coordination in all conditions. Software embedded in the Emax 2 also optimises the microgrid where locally generated power, energy storage, loads and util- ity power work together. ABB algorithms measure and evaluate energy consumption, enabling constant power loads or peak power reductions, depending on users’ requirements. Frisio adds: “Emax 2 will make managing power consumption and renew- able energy sources simpler and more effective. It will also help end-users to take maximum advantage of the opportunities that renewables present.”
